Description

High - quality fumed silica with a remarkable 99.8% purity and excellent adsorption properties has become an indispensable reagent in the adhesive and silicone sealant industries.

In adhesive formulations, this fumed silica serves as a highly effective thickening agent. Its large specific surface area and strong adsorption capacity allow it to interact with the adhesive matrix, increasing the viscosity and preventing sagging or flow during application. This ensures precise and controlled bonding, especially in vertical or overhead applications.

For silicone sealants, the addition of high - purity fumed silica enhances their rheological properties. It provides the sealant with the right consistency for easy dispensing and smooth application, while also improving its stability and shelf - life. Moreover, its non - reactive nature ensures compatibility with a wide range of silicone - based formulations. With its superior performance, high - purity fumed silica is a top choice for manufacturers aiming to produce high - quality adhesives and silicone sealants.
